LaetitiaConstant/yuka — reverse-engineered prompt

Build me a React Native Expo app that works like a simple Yuka clone for iPhone. I want to scan a food product barcode with the camera, including a torch option, then use the OpenFoodFacts API to show the product details and nutritional values in a clean mobile screen.

Please include a scan history so I can see products I already scanned, and let me mark products as favorites and view them later. Keep the design simple and close to a consumer food scanner app, with clear product names, images if available, nutrition info, and helpful empty states when nothing has been scanned yet.

It only needs to be reliable on iOS for now. Use Expo so I can run it with Expo Go or the iOS simulator. Look up current Expo and OpenFoodFacts docs online if you need to.
